Active Pharmaceutical Ingredients (API)
API's are typically produced by extraction or chemical syntheses. In most cases afterwards the material is crystallised, mechanically separated and afterwards dried. These steps can often be replaced by spray drying which not only allows to control the humidity or residual solvent content but additionally also to create materials with a tailor made particle size distribution and a dominant amount of amorphous material.

Finished Drug Products
Finished drug products are produced by mixing/blending API with excipients (polymers, fine chemicals, etc.), solvents and others according to a specific formulation, after which one or several process stages follow until the final dosage form is reached.
